Subject: Re: Anyone have source for stock & ported 113 head #s? (pics added) by cuisinartvette on 2008/9/4 4:17:40 Spent two hours up there, interesting. I was a little disappointed but being as I havent done a valve job, they have small valves and this was my initial cut....in comparison with the ported big valve head #s numbers it isnt too terribly bad. To think these are in the ballpark of the aftermarket head is nuts. Even if a TPI couldnt use all the peak #s of one the lower lift numbers that a TPI loves would still kill a good set of ported factory heads. Just my .02, Im no pro. Little more work and they will be satisfactory to me for what this guy is doing. (Ported TPI base, 214/228 HR 520/530 lift.). Look at all numbers, not just peak. Anesthese, if these arent TPIS correct me, I ASSumed lol.
